Da Vinci 3d Printer Pulley Shim

This is a shim for the pulleys that drive the Y axis on the Da vinci 1.0 3d printer. Nice and simple to install. Just snaps in place in between the pulley and snap ring on the three pulleys in the back of the machine. Make sure you install it on the side that does not have the black pin in the pulley. Using these will take backlash out of the belt drive system making your parts print better.
